Depression and suicide facts

Depression is more common than AIDS, cancer, and diabetes combined, and nearly 400,000 people attempt suicide in the U.S. every year.

But even though it's a common and serious problem, many people don't know that much about depression and suicideincluding who's at the greatest risk, why, and when they are most likely to be vulnerable.

Depression and suicide facts

Depression is more common than AIDS, cancer, and diabetes combined, and nearly 400,000 people attempt suicide in the U.S. every year.

But even though it's a common and serious problem, many people don't know that much about depression and suicideincluding who's at the greatest risk, why, and when they are most likely to be vulnerable.

Suicides peak during holidays

Myth

"There is a time of year when suicides are more common," says Marcia Valenstein, MD, research scientist at the Department of Veterans Affairs Health Services Research & Development Service. "But it's not when everyone thinks."

Most people think the winter holidays are a risky time, but suicides are lowest in December and peak in the spring.

It's not clear why, but it could be due to changing levels of natural light. "It could be that they have more energy to attempt suicide," says Dr. Valenstein, who is also an associate professor of psychiatry at the University of Michigan Depression Center, in Ann Arbor.

Suicide rates climb with altitude

Fact

The greater the elevation of a person's home, the higher the risk of suicide, according to a recent study. Suicide rates are about 70% higher in regions 2,000 meters in elevation, for example, compared to at sea level.

The effect appeared to hold even after researchers accounted for risk factors such as greater gun ownership and lower population density.

Teens are at greatest risk

Myth

Teenage suicides make headlines, but the elderly are more likely to take their own life than any other age group, says Dr. Valenstein.

At particularly high risk are white men over the age of 85, who have a suicide rate of 49.8 deaths per 100,000, compared with about 14 per 100,000 in people over 65, and 11 per 100,000 in the general population.

Still, teenagers remain a high-risk group. One in five high school students says he or she has considered suicide in the past year and 1 in 12 attempts to take his own life. (The suicide rate for 15- to 19-year-olds is 6.9 per 100,000.)

Writing style is linked to suicide risk

Fact

Creativity, depression, and suicide have long been linked, so it may come as no surprise that some of history's most creative individuals suffered from a mental illness. Depression affected great minds such as Charles Dickens, John Keats, and Tennessee Williams.

Several famous writers have committed suicide, including Ernest Hemingway, Sylvia Plath, and David Foster Wallace. This group also has something else in common: They all wrote in the first person, which has been suggested to be a sign of suicide risk.

Poor countries have higher suicide rates

Myth

In fact, many rich countries have higher suicide rates than developing nations.

Some of the lowest rates can be found in Latin American countries, such as Brazil and the Dominican Republic, while richer countries (based on their GDP per capita), such as Russia, Japan, and France, are among the highest. These nations report numbers between two and three times as high as the U.S.

Approximately 54 of every 100,000 men in Russia, for example, commit suicide every year. (The region's high rates of alcohol consumption may be partly to blame.)

Suicide is more common than in the past

Myth

Suicide rates in the U.S. have remained relatively constant over the past several decades, and may even have slightly decreased.

Still, youth between the ages of 15 and 24 are more than twice as likely to commit suicide today compared to 50 years ago. And, worldwide, suicide rates have increased by about 60% in the last 45 years, according to the World Health Organization.

Treatment cuts suicide risk

Fact

"There are not a lot of ways to prevent suicide at this point," says Dr. Valenstein. "But successful treatment of any underlying psychiatric disorder is very important and can reduce suicidal thoughts, particularly among older people."

She adds that a popular concern that antidepressants can actually raise the risk of suicide among patients under the age of 25 is most relevant during the first few weeks of therapy.

Suicides can trigger "copy cat" attempts

Fact

Exposure to others who have committed suicide may "reduce some of the barriers to people thinking of doing it," says Dr. Valenstein.

She points out that this link has helped write new rules for responsible journalistic reporting. For example, journalists now typically refrain from going into detail or sensationalizing death from suicide.

"They usually finish up any story with a reference to a hotline so that distressed people reading it will reach out for help rather than being tempted to emulate," Dr. Valenstein adds.

Suicides are more common on weekends

Myth

While Wednesdays are notorious for being "bumpy," and Tuesdays, in some studies, have been found to be the deadliest for suicides, Dr. Valenstein and her colleagues identified a different weekly peakMonday.

In an unpublished study that they recently completed, they found that the most suicides fall on Mondays.

Dr. Valenstein says that, while it is not clear from studies so far which day is most common for suicides, they do seem to occur near the beginning of the week. "I would assume that the start of the work week is a more stressful time for people."

Men are at greater risk

Fact

While three times more women than men attempt suicide, four times more men than women actually kill themselves.

More than half of suicides in the U.S. are completed with guns. This violent and usually irreversible route is the choice of most men. However, Dr. Valenstein notes that the most common method among women is poisoning, typically an overdose of medication, the result of which is less often lethal.
